Fireproof and anti-electric shock protector

The utility model discloses a fireproof and anti-electric shock protector in the technical field of relay protectors, which comprises a home-entry switch connected with a zero line N and a live line L. The output terminal of the home-entry switch is connected with an arc extinguishing protector and is used for monitoring the current of a power utilization line in real time and carrying out current limiting protection on the line. One end of the induction part is connected with a circuit breaker protector assembly and used for controlling on-off of load current, and one end of the circuit breaker protector assembly is electrically connected with a relay assembly. According to the utility model, the open circuit protector assembly is started to prevent the load assembly from being damaged due to overhigh temperature, and the air switch is applied to a single-phase AC electrical circuit to avoid fire hazard caused by short circuit of a phase line or a null line and a live line, so that the problems of large shor
